What Home Addition Work Covers

Room additions are commonly chosen by homeowners who need more room but aren't ready to move. They're also a popular here choice for homeowners planning to age in place. No matter the size, the process follows a well-defined set of phases that we have executed on hundreds of projects.

Is a room addition the same as a renovation?A room addition physically expands your home's overall footprint by extending the structure beyond the current walls.
